WATER-CHECK.

Specification of Letters Patent.

Patented May 23, 1911.

Application filed November 16, 1910. Serial No. 592,642.

To all whom it may concern:

Be it known that 1, JOHN E. OHLSON, a citizen of the United States, and a resident of Twin Falls, in the county of Twin Falls and State of Idaho, have invented a new and Improved Water-Check, of which the following is a full, clear, and exact description.

My invention relates to a check to be used in connection with irrigating ditches.

One object of my invention-is to provide means for controlling the passage of water from a distributing ditch into lateral furrows, and also to provide means for protecting the adjacent edges of the furrows, whereby the rush of water will not carry away the surrounding soil, and further, to obviate the labor and expense of constructing and tearing up mud dams, as heretofore has been done.

A further object is to provide a simple, cheap and effective gate, and one which may be readily and cheaply constructed.

With the above and other objects in view, as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the accompanying drawings, forming part of this specification, the reference char acters of which indicate corresponding parts in the several figures :--Figure 1 shows one application of my device to a distributing ditch and furrow; Fig. 2 is a longitudinal sectional view of my improved check in position at the mouth of a stream or furrow; and Fig. 3 is a front elevation of my check, a perspective view of which is shown in Fig. 4.

My improved check comprises a plate 1, having an aperture 2 in the upper part thereof, he lower part of which is bent outwardly into a V-shaped projecting and offset anchor portion 3, the unbent portions of the plate, on each side of the partition 3 forming wings 4. Forming the outline of the lower portion of the aperture 2 and integrally connected with the anchor portion 3, is a V-shaped trough 5 extending at right' angles to the plane of the plate 1. The front 6 of the anchor portion 3 is of less height than the portion adjacent the wings 4, whereby the upper edge of the anchor i portion 8, and therefore the front edge of the trough 5, is given a downwardly-converging outline 7. The free end 8 of the trough 5 has its upper end beveled off, and this end is converged as shown at 10, in order to form a small channel opening 11, or these ends may be left open, as shown in Fig. 4, so as not to present shoulders for the collection of trash floating on the water. It will thus be seen that my improved check may be inserted at the end of a furrow, and the anchor portion 3, together with the wings 4, may be forced down into the adjacent ground as far as may be necessary. The upper portions of the wings 4, as shown in Figs. 1 and 2, may overlap the top edge of the adjacent banks to form a head to prevent the bank from washing away at that point. If it is desired to retain the water in the distributing ditch and to prevent it from flowing into the furrows, it is only necessary to raise my check, as shown in dotted lines in Fig. 3, or by only partially raising it, the amount of water flowing from the distributing ditch into the furrows may be regulated, depending upon the height to which the trough is raised.

As many changes could be made in the above construction, and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matters contained herein in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is merely intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween, and that materials, sizes and relativities of parts are non-essential, except as called for in the claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a water check, a plate having an aperture therein, that portion of the plate which defines the lower portion of said aperture being ofiset to one side of the remaining portion of said plate, to form an anchor, and an open top trough integral with said offset portion and extending beyond the sides of said plate.

2. In a water check, spaced-apart wings, a trough positioned between said wings and integral therewith, and a V-shaped anchoring means disposed at an angle to said Wings connecting and bracing the same. 7

3. In an irrigation device, wings spaced apart, an anchor portion ofiset from the plane of said Wings and connecting said wings, and a water-conveying trough integral with said wings and supported by said 10 portion.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN EVALD OHLSON.
